I'm amazed at how loud it is. Battery life will easily last several hours. Only downfall is your phone or device has to be pretty close to it (I'd say within 15 feet), which kind of defeats the bluetooth purpose.

We went and got the cheapo ones from Big Lots for $20.00. Sylvania brand I think? We've used it with an Ipad and had it on for 8 hours straight without killing the battery. Good and loud too. Recharges in a couple hours with the same Ipad charger.

I just bought one of these, but mine was the $59 one. I really like it, but I ran the battery dead and it wont recharge now. Going to take it back to Best Buy, but I will try to get another one. they are cool because you can blue tooth them to another one of the same speakers and double the sound and have stereo.
